Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the prior art, the viscosity of the coating is greatly influenced by human or environmental factors, for example, the solvent-type coating is fast to volatilize, the solvent content is directly influenced by the measuring time, and the viscosity is easily increased when the operation is slow. The viscosity cup is made of metal and is unstable in temperature in air.

Aiming at the problem that the accuracy of the detection result is not high due to the factors, the invention provides the automatic measuring device for the viscosity of the coating, which can reduce the artificial influence factors when the viscosity of the coating is measured and improve the accuracy of the measurement result of the viscosity of the coating by arranging the first sensor 4 to measure the first time information when the coating in the viscosity cup 2 starts to flow down and the second time information when the coating stops flowing down.

Referring to fig. 1, an embodiment of the present invention provides an automatic paint viscosity measuring device, including a receiving cup 1 and a viscosity cup 2 for accommodating a paint to be measured, and further including: the base 3, supporting component and first sensor 4, the supporting component is connected with base 3, receives cup 1 and sets up on base 3, and viscosity cup 2 and first sensor 4 are located on the supporting component, and the height of first sensor 4 relative to base 3 is less than the height of viscosity cup 2 relative to base 3, and first sensor 4 is used for measuring the first time information that the coating in viscosity cup 2 began to flow down and stops the second time information that flows down.

In this embodiment, a T-4 (paint-4) cup is used as the viscosity cup 2, but this embodiment is not limited thereto, and in other possible embodiments, other types of viscosity cups 2 may be used.

Specifically, the base 3 is horizontally disposed to ensure that the receiving cup 1 provided on the base 3 is stably placed in a horizontal plane. In this embodiment, in order to further ensure the horizontal placement of the base 3, two horizontal adjusting bolts 15 are arranged on the base 3, the two horizontal adjusting bolts 15 are arranged at two ends of the base 3, and the horizontal height of the base 3 can be flexibly adjusted by adjusting the horizontal adjusting bolts 15.

In the present embodiment, the first sensor 4 is provided on the support member, and the first sensor 4 may be engaged with the support member by an engaging member, for example. As an alternative embodiment, in another possible embodiment, the first sensor 4 can also be fixed to the support component by means of screws. It is worth noting, however, that in setting the first sensor 4, care should be taken to control the height of the first sensor 4 relative to the base 3 to be less than the height of the T-4 cup relative to the base 3. That is, the first sensor 4 is set to be lower than the outflow port of the T-4 cup by a certain distance, and in the present embodiment, the first sensor 4 is set to be lower than the outflow port of the T-4 cup by 2mm, so as to ensure that the first sensor 4 can accurately measure the first time information of the start of the flow of the coating material and the second time information of the end of the flow of the coating material, thereby avoiding the blockage. However, the present invention is not limited to this distance, and the distance may be adjusted to some extent in other possible embodiments.

As an alternative embodiment, in another possible embodiment, a level can be placed on the T-4 cup, and the adjustment result can be more accurate by adjusting the level adjusting bolt 15 according to the display result of the level.

Optionally, the automatic coating viscosity measuring device further comprises a material blocking sheet, and the material blocking sheet is arranged on the outflow port of the T-4 cup. By arranging the material blocking piece, the condition that the coating is stained on the body of a worker due to the fact that the worker blocks the outflow port of the T-4 cup by hands can be avoided. The volatilization speed of the solvent-based paint can be reduced, and the influence of the volatility of the material on the experiment can be reduced. In the embodiment, the material blocking piece can be arranged at the flow outlet of the T-4 cup through the pin shaft, and the material blocking piece is pulled out when a test is started.

In the present embodiment, the first time information measured by the first sensor 4 is used as the time when the paint starts to flow down, the second time information is used as the time when the paint stops flowing down, and the time when the paint flows from the T-4 cup to the receiving cup 1 can be accurately obtained from the time difference between the first time and the second time. The automatic determination of the viscosity of the coating is realized, the error of human factors is avoided, and the measurement result is more accurate.

The first support 5 is connected with the base 3 through a height adjusting bolt 11, and the height of the first support 5 can be adjusted through the height adjusting bolt, so that the heights of other devices arranged on the first support 5 are indirectly adjusted. It should be noted that when the T-4 cup is placed, the height adjusting bolt is adjusted to adjust the distance between the T-4 cup and the receiving cup 1 to be about 5cm, so that the splashing condition caused by too large height difference when the coating flows down can be avoided, and the safety of the test is ensured.

As an alternative embodiment, the automatic paint viscosity measuring device further comprises a second sensor 8, the second sensor 8 is arranged on the third support 7, and the height of the second sensor 8 relative to the base 3 is larger than the height of the receiving cup 1 relative to the base 3.

That is, the second sensor 8 is set to be higher than the receiving cup 1 by a certain distance, and in this embodiment, the second sensor 8 is set to be higher than the receiving cup 1 by about 2mm, so as to ensure that the second sensor 8 can accurately measure the third time information when the coating material stops flowing down, and avoid being blocked. However, the present invention is not limited to this distance, and the distance may be adjusted to some extent in other possible embodiments.

In an alternative embodiment, the first time information measured by the first sensor 4 may be used as the time when the paint starts to flow down, and when the time when the paint stops flowing down is determined, the first sensor 4 and the second sensor 8 may measure the time together, and the data measured by the sensor that received the time information first may be used as the standard. By arranging the two sensors, the accuracy of the measurement result can be further improved.

Specifically, the first sensor 4 and the second sensor 8 may be infrared sensors or other sensors capable of achieving the same purpose, and are not limited herein.

Optionally, the automatic measuring device for the viscosity of the coating material further comprises a display screen 9, and the display screen 9 is arranged on the second bracket 6 and is respectively connected with the first sensor 4 and the second sensor 8. The first time information, the second time information or the third time information are displayed through the display screen 9, so that a worker can intuitively master the conditions that the coating starts to flow down and stops flowing down, and the reading error of the stopwatch can be effectively eliminated.

In this embodiment, the automatic coating viscosity measuring device further includes a rib 10, one end of the rib 10 is connected to the first bracket 5, and the other end of the rib 10 is connected to the second bracket 6. The connection of the first bracket 5 and the second bracket 6 can be more stable by the reinforcing ribs 10.

Optionally, the automatic measuring device for the viscosity of the coating further comprises a constant temperature device, and the constant temperature device is arranged on the supporting assembly and sleeved on the outer side surface of the T-4 cup.

Specifically, the constant temperature device comprises a constant temperature sleeve 12, a heating pipe and a circulating pump, the constant temperature sleeve 12 is arranged on the supporting component and sleeved on the outer side surface of the T-4 cup, the heating pipe is arranged on the constant temperature sleeve 12 and used for circulating constant temperature liquid to heat the T-4 cup, the heating pipe comprises a water inlet 13 and a water outlet 14, and the circulating pump is connected with the constant temperature sleeve 12 through the water inlet 13 and the water outlet 14. Through setting up constant temperature cover 12 can reduce viscosity cup 2 and for the environmental impact that the unstable temperature leads to of metal material in the air, promote the accuracy of survey.

Wherein, the circulating pump is arranged in a constant temperature water area, and the temperature value of the constant temperature water area is 23 +/-2 ℃. By arranging the constant temperature device, the temperature of the coating in the T-4 cup can be kept, and the influence on the characteristic of the coating due to the temperature change is avoided, so that the test result is influenced.

When the paint is used, firstly, the T-4 cup is wiped clean by using absolute ethyl alcohol, the T-4 cup is placed in the constant temperature sleeve 12 for about 20 minutes to be subjected to constant temperature, after the T-4 cup is taken out, the paint to be detected is drained into the T-4 cup by using a glass rod, the liquid level of the paint is slightly higher than the cup mouth of the T-4 cup, and the cup mouth of the T-4 cup is covered by using a glass plate. The volatilization speed of the solvent type coating can be reduced by arranging the glass plate, and the influence of the volatility of the material on the experiment is reduced. The T-4 cup is then placed in the thermostatic jacket 12 so that the outflow opening of the T-4 cup is aligned with the receiving cup 1. In the process, the constant-temperature water area is communicated through the heating pipe, the circulating pump sends the water pressure in the constant-temperature water area to the heating pipe for circulation, and the constant-temperature heating of the constant-temperature sleeve 12 and the T-4 cup is realized.

Further, the material blocking piece is poked and the glass plate is horizontally pushed, so that the coating naturally flows down under the action of gravity, and the start time and the end time of the coating flowing down are obtained through the first sensor 4 and the second sensor 8, so as to finish the measurement.
